Google Mobile goes Voice Activated

I have now upgraded to the iPhone GS, and it is better becasue of the battery life and spped, but not a quantum leap. What still keeps me firmly in the Apple camp are the applications. Another, and there are many, essential applications is Google mobile. It is differnet than Google earth. On this you hit the microphone icon and it ask you to talk into a phone. Say an address and the map comes up and you can ask for directions. Want to know where the doctor's office is becasue you forgot? Speak their name and it tells you. The obvious advantage here is not having to do the normal Google search while you are driving. You can speak and watch the road at the same time. The best part is that it is free. Google mobile, don't leave home without it.
